Specification of Letters Patent.

Patented Nov. 6, 1906.

I 1'0 all whom it may concern.-

Be it known that I, ALFRED SWAN, a subject of the King of Great Britain,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Machines for Basing IncandescentLamps, of which the following is a specification.

This invention relates to machines for aplying bases to the bulbs ofincandescent amps; and its object is to provide a machine for doing thiswork instead of doing it by hand, and in this way to greatly reduce thecost of basing lamps, to increase the number of lamps that an operatorcan base in a given time, and to insure firmly uniting the base to thelamp-bulb, with its axis coincident with the axis of the bulb.

The type of lam -base now in common use consists of a meta lic shellclosed at one end by a web of insulating material, through which is asmall opening for one of the leading-in wires of the lamp. Locatedcentrally in this web is the center metallic contact of the base, whichmay be applied thereto either before or after the base is secured on thelampbulb. The neck of the bulb is inserted in the other end of the shelland the shell is held firmly thereto by cement.

Prior to my invention the work of ap lying bases to incandescent lampswas d bne largely by hand. The base was partially filled with a hotplastic cement compound and placed over the neck of the lamp, andpressure was then applied to hold it firmly thereon while the cementcompound cooled and hardened. Basing lamps in this way has always beenslow and expensive, and, moreover, it often happens that the base is notperfectly straight on the bulb. To overcome these-disadvantages, I haveprovided a machine for doing this work. In operating with the machine Iuse a hard pellet of coment compound which can be dropped into the lampbase and afterward softened by heat. This pellet, which is somewhatsmaller than the base of the lam and pro vided with an opening theretfirough, is dropped into the base, and one of the leadingin W1IeS lSthreaded through the opening therein and the small opening in the centerof the base. The arts are held together by one or both of the eading-inwires while they are passing through a heater which softens the pellet.The bulb, with the base hanging thereto, is then automaticallytransferred to a machine, by which the bulb and base are pressedtogether, and while in this machine the cement is cooled, and thushardened, whereupon the based lamp is automatically ejected from themachine.

The details of construction and the mode of operation of my improvedbasing-machine will be better understood by reference to the followingdescription, taken in connection with the accompanying drawings, whichshow the preferred embodiment of my invention.

In the drawin s, Figure 1 is a plan view of the machine bro e11 away inpart. Fig. 2 is an enlarged plan view of a portion of the same. Fig. 3is a detail view of the carrier. Fig. 4 is a sectional elevation of thecarrier and the -means for transferring the lamps from the carrier tothe machine. Fig. 5 is a front elevation of the plunger shown in Fig. 4.Fig. 6 is a sectional view of the basing-machine. Fig. 7 is an enlargedsection of one of the pressing and cooling devices. Fig. 8 is anelevation of thesame. Fig. 9 is a plan view of one of the rece tacles.Fig. 10 is a horizontal section of the machine, showing a portion of theoperating mechanism. Fig. 11 is a detail view of one of the pairs ofgears shown in Fig. 10, and Figs. 12 and 13 are a horizontal section andan elevation of the mechanism for operating the compressingplungers.

Referring to the drawings, 1 indicates a supporting member mounted forrotation and driven by a belt 2 from any suitable source of power. Themember 1 is rovided with a plurality of receptacles for t e lamps to bebased. In the present machine I have shown twenty four of thesereceptacles; but the number may be varied as desired. The periphery ofthe member 1 is formed with teet constituting a gear 3, which mesheswith a gear-wheel 4, secured on a shaft 5, and thus drives the carrier.This carrier consists of an endless-chain 6, running 011 a sprocketwheel7, secured to shaft 5, and a plurality of idle sprocket-wheelsS, whichguide the carrier back and forth through a heater 9, heated by ranges ofsteam-pi es 10. Secured to chain 6 are a plurality o holders 11, asshown in Figs. 3 and 4, for supporting the bulbs of incandescent lamps.On the supportingposts of alternate holders are short shafts eachcarrying a roller 12 on each end, and within the heater suitable tracks12 are arranged adjacent to the path of movement of through the heater,where the cement is sottened, and as each holder reaches the line ofcenters of the member 1 and wheel 4 devices are operated automaticallyto push the lamp from the carrier into a receptacle on the supportingmember. These devices consist of a plunger 13, which is reciprocated bycompressed air and which carries on its upper end a piece of heavy felt14, adapted to strike the end of the bulb and tilt it in the holder, sothat it slides into the receptacle. This plunger is carrier by an arm15, on which is mounted a cylinder 16, in which a piston 17 on the endof the plunger-rod 13 moves.

valve 18, located in a bore in arm 15, is operated to admit air to andpermit its exhaustion from either side of the piston. This valve isnormally held at one of the limits of its movement by a spring 19, Fig.5, and depending from its end is a projection 20, which is engaged bypins 21 on the wheel 7 to turn the valve on its axis to the positionshown in Fig. 4 and then release it, whereupon the spring 19 retracts itto its former position. Air under pressure is led to the valve 18 by anair-supply pipe 22. In the position of the valve shown in Fig. 4 apassage-way 23 connects the air-supply pipe 22 with an opening 24,leading to the under side. of the piston 17, and two passage-ways 25connect openings 26 to the upper side of the piston with openings 27 tothe air. When valve 18 is shifted by s ring 19 to the position shown inFig. 5, these connections are closed, and two passage-ways 28 connectthe air-supply pipe 22 with the openings 26 to the upper side of thepiston 17, and two passage-ways 29 connect openings 30 from the underside of the piston 17 to the air. It will thus be seen that in oneposition of the valve air is admitted to the under side of the pistonand exhausted from the up or side, so that the rod 13 is pushed up, andits felt-covered end hits the bulb and slides it out of the holder, andin the other position of the valve air is admitted to the upper side ofthe iston 17 and exhausted from the under si e, so that the rod 13 ismoved down again. As there are two pipes leading to the upper side ofthe piston, air is admitted freely, and the downward movement of the rodis efi ected very quickly, so that the end of the plunger is withdrawnimmediately from the path of movement of the holders 11. The parts areso arranged that successive receptacles on the member 1 and successiveholders 11 arrive at the line of centers of member 1 and wheel 4together, and when in this position the plunger 13 is operated by theengagement of one of the pins 21 on wheel 7 with the projection 20 onvalve 18. A pipe 30 connected to a source of supply ofcompressed air,directs a blast against each bulb as it drops into its receptacle toassist in positioning it properly therein.

The machine for pressing the lamp parts together and cooling the cementconsists of a standard 31, Fig. 6, carrying a lower plate 32 and anupper plate 33, in which arebearings for a hol ow vertical shaft 34. v Awatersup ly plpe 35 connects with the lower end of t e s aft 34, asuitable stufling-box 36 beingfprovided to prevent leakage. Keyed to shat 34 is a worm wheel 37, with which meshes a worm 38 on the drivin shaft39 of the machine, which carries a pul ey 40 and is driven by the belt2, running on the ulley. Secured to the upper end of the sha t 34 is themember 1, which carries the receptacles for the lamps. A cylindricalcasting 40, mounted on the upper plate 33, has its top machined to forma bearing for the member 1, which rests thereon. Each of the twentyfourreceptacles consists of a hollow cylinder 41, Figs. 7 and 9, located inan opening in member 1 and having a flange 41 at its upper end, whichrests on the upper surface of the member. Vertically movable within thereceptacle is a hollow plunger-rod 42, having an extension at its lowerend which slides in a bearing formed in a depending portion 43 of themember 1. A spring 44 is attached at one end to the plunger-rod and atthe 3 other to a bracket secured to the depending portion 43 and tendsto pull the plunger-rod 42 downward in the receptacle 4 1. Fastened tothe rod 42 isa bolt 45, carrying a roller 45,-

which 006 erates with a cam-surface to position the p unger-rod. Movablevertically in the opening in the lunger-rod 42 is a sleeve 46, the upperend 0 which is formed to fit the closed end of the base of a lamp, and acoiled spring 47 within this sleeve engages a shoulder on the sleeve atits upper end and the bottom of the opening in the plunger-rod at itslower end and tends to force the sleeve upward in the o ening in therod. In the sleeve 46, the p unger-rod 42, and the receptacle areopenings which when the parts are in the position shown in Figs. 7 arein alinement with each other and with an opening in a chamber 48, whichis connected by a pipe 49 with an member 1, a cylindrical casting 50,carried thereby, and a cover-plate 51. The top of shaft 34, which entersthis chamber, is closed by a plug 52. A pi e 52' extends through thecasting 50, the p and forms a passage-way for oil for lubricating theupper bearing of shaft 34. Extending into an opening in the cover-plate51 is a air-chamber formed by the ug 52, and the sha-ft 34 I on the rod76 and rotatable in a bore in the cross-head 76. Vertical movement ofthe sleeve 7 7 independent of the cross-head is prevented by a hub 82,secured to the lower end of the sleeve, to which is secured the end i ofa flexible cord 82, which extends partially around the hub in a groovetherein, then through an opening in the link 81 and has its end'attachedto the end of a coiled spring 83,

I the other end of which is secured to a pin on the link 81. Thus if aroller 71 engages the projection 77 the sleeve 7 7 carrying theprojection, is turned on the rod 76 to permit the roller 71 to pass by,and as the spring 83 is put under tension when the sleeve is turned thisspring draws the sleeve and projection back to their normal positions assoon as the roller 71 releases it.

The' means for positioning the lower plunger-rods 42 consists of a cam84, formed on the edge of the upper plate 33, on which the rollers 45,secured to the plunger-rods, roll. In the position where thelamps aretransferred from the carrier to the machine by the mechanism abovedescribed this cam is cut away, as shown in Fig. 13, so that eachplunger-rod is dravm down in its receptacle by its spring 44 to permitthe lamp to fall in proper position in t 1e receptacle. Immediatelyafter passing from this position each roller 45 rolls up an incline 84on the cam 84, so that plunger 42 is raised vertically and pressesagainst the base of the lamp. At the top of this incline the camsurfaceis horizontal around more than three-quarters of the circumi'erence ofthe machine, and as the roller 45 is moving along this surface the bulband base are pressed together, and the cement is cooling. The rod 69 isthen pulled down by cam 75, and latch 7 2 is pressed back. Cam thenreleases arm 65, and spring 71 pulls arm 65 and the rod 69 and cap 67,secured thereto, up, so that the lamp is then ready to be ejected fromthe machine. The means for accomplishing this consists of a rod 85,movable vertically in ways and forming a movable section of the cam 84.Rod 85 is reciprocated vertically by a cam 86, Fig. 6, keyed to theshaft 79 and provided with a cam-groove, into which a pin 87 on the rod85 extends. In the rod 85 is a groove or pas- I sage-way 88, which whenthe rod is in its uppermost position, as shown in Fig." 6, connects theend of pipe 63 with a pipe 89, leading from a source of supply ofcompressed air 90. Thus when the roller 71 moves onto the end of the rod85 the rod-is raised vertically by cam 86, pushing the lamp up inthereceptacle. As the rod 65 reaches the up er limit of its movement air isadmitted i iom the source 90 through the pipe 89, passage-way 88, pipe63, and the pipe 62 opposite the lamp, and the blast of air from ipe 62blows the amp over into a'chute 91, own which it slides onto a belt 92,-driven by a pulley 93, and belt 94 from a pulley 95 on t e powershaft39. When the lamp is ejected, the plunger-rod 42 is drawn down again toits original position by the cam 86, and the rol er 45 moves onto thestationary portion of the cam, which is here cut away to allow the pluner-rod to be drawn down in the receptacle y its spring 44 to permitanother lamp to be inserted therein.

The operation of the machine as thus constructed will be understood fromthe foregoing description.

The parts for the lamps are assembled as shown in Fig. 4. The pellet 96,of cement compound, is dropped into the base 97, and one of theleading-in Wires 98 is threaded through the opening in the pellet andthe openingin the base of the lamp. I prefer to place a small thinwasher 99, of paper or other suitable material, on each side of thepellet 96 to prevent the cement when softened from running up or downalong the leading-in wire. The other leading-in wire is soldered to theshell of the base and holds the base on the bulb, or it may be bent backalong the bulb, so that it may be soldered to the base after the latterhas been secured to the bulb, and the parts may be held together bybending over the wire extending throu h the o ening in the centercontact. T e parts or the lamps thus assembled are placed on the holders1 1 and carried thereby through the heater, where the pellets 96 aresoftened. As each lamp comes opposite the plunger 13 one of the pins 21on wheel 7 operates the valve 18, and the plunger is raised until ithits the end of the bulb and-slides it off of the holder and into areceptacle on the basingmachine. The wires 61 and the blast of air frompipe 30 guide the base parts into the receptacle properly, Thus eachreceptacle as it comes op osite the plunger 13 is sulp plied with thease and bulb for a lamp, t e base containing just the amount of thatsoft cement compound necessary to hold the base firmly on the bulb. Thelower plunger-rod 42 of each'receptacle is in its lowermost positionwhen the lamp parts are supplied thereto, as the roller 45 on the rod isthen on the cut-away portion of the edge of the upper plate 33, whichforms the cam84. Also the cap 67 is held in the raised position by thespring 71. As each receptacle is moved from this position the roller 45travels up the incline 84 of the cam 84, thus ralsmg the lowerplunger-rod 42 until the top of the sleeve 46 therein engages the baseof the amp. The roller 71 on the end of the rod pipe 53, which connectswith an air-supply pipe 54, a suitable stuffing-box 55 being provided toprevent leakage of air at the joint. In the receptacle 41 is a chamber56, (shown in dotted lines in Fig. 9,) which extends almost entirelyaround the opening in the receptacle. Pipes 58 and 57 connect with theends of this chamber, pipe 57 being connected to the opening in thehollow shaft 34 and pipe 58 with a chamber formed by the upper plate 33,the cylindrical casting 40, and the memher 1. A waste-pipe 59communicates with this chamber. Extending from the top of each of thereceptacles 41 down a short distance to the opening therein are aplurality of passage-ways 60 to permit the escape of gases which mayaccumulate in the receptacles. Secured in the top of the receptacle areguide-wires 61, which guide the bulb into its proper position in thereceptacle when it is transferred thereto from the carrier. Arrangedadjacent to each receptacle is an L- shaped tube 62, open at both ends,the upper end of which is directed toward the position of the top of abulb held in the receptacle. The lower end of each of these tubesextends through the member 1, so that when the receptacle correspondingto that tube is in the position for ejecting the lamp therein the lowerend of the tube 62 is in alinement with an air-pipe 63. Mountedvertically between the member 1 and the top plate 51 are a plurality ofrods 64, one for each receptacle, on each of which is slidingly mountedan arm 65, having a long bore in its outer end in which is the upperplunger-rod 66. At its lower end rod 66 carries a cap 67, adapted to fitover the top of the lamp-bulb. A spring 68 is arranged between ashoulder on rod 66 and the top of the opening in arm to press the rodand the cap carried thereby downward. The upper and lower plunger-rods,the cap 67 ,and the sleeve 46 are all in axial alinement. Secured toeach arm 65 is a rod 69, theupper end of which extends up through anopening in the top plate 51 and carries the piston 69 of a dash-pot 70.The dash-pot is entirelyclosed, except for a small opening 70 a shortdistance below its upper end. A strong coiled spring 71 has one endattached to the top of the dash-pot 7 O and the other end to the arm 65to pull the arm 65 and all the parts secured thereto upward. The lowerend of rod 69 extends down through an opening in the member 1 andcarries a roller 71, by which the rod and the arm 61 are drawn down topress the lamp-bulb into the base. When the arm is drawn down, it isheld in thisposition to keep the bulb andbaseunder compression while thecement in the base is cooling and hardening. The means for doing thisconsists of a hook 72, secured to the rod69, and a latch 72,urgedforward in asuite able casing by a spring 73. The latch 72 has a stud 73extending through a slot in the ceptacle has been based and has arrivedat the position for ejecting. In order that the cooperating edges of thehooks 72 and the latches 72 may not be worn off, as they would be if therods 69 were suddenly released by pulling the latches 72 back, I providemeans for relieving each latch of the strain of the hook just before therod starts on its upward movement. Mounted on the upper plate 33 inposition to engage the roller 71 of each rod 69 just before the dog 74corresponding to that rod engages'the post 74 is a cam75, under whicheach roller 71 passes and by which the roller and the rod 69, to whichit is secured, are drawn down enough to carry the hook 72 on the rod 69away from its latch 72. \Vhile held in this relation by the cam 75, thedog 74 is operated by post 74 to press the latch 72 back out of the pathof movement of hook 72. The rod 69 can then be drawn upward free oflatch 72. In order that this upward movement may start slowly, the cam75 is extended, and this extended portion is inclined to the horizontal,as shown in Fig. 13, so that as the movement of the roller under the camis continued the spring 71 draws the arm 65 and the rod 69 up. As theroller passes out from under the cam the arm and rod are quickly drawntothe uppermost position, this movement being cushioned by the dash-pot70.

The mechanism for pulling the rod 69 down, so as to bring the cap 67over the bulb of the lamp, in which position the rod is locked by thehook 72 and latch 7 2, consists of a cross-head 76, Figs. 12 and 13,movable vertically upon rods 76 and provided with a projection 77, underwhich each roller 71 on the end of a rod 69 moves. On the driveshaft 39,Fig. 10, is a inion 78, which meshes with a gear 78 on a s aft 79. ()nthe end of shaft 79 is one of a pair ofintermittent gears 80 and 80.(Shown in detail in Fig. 11.) The gear 80' is carried by a short shaft80", mounted in a bearing on the lower plate 32. The arrangement ofthese gears is such that the gear 80 makes one complete revolutionduring a half-revolution of the gear 80 and remains at rest during theother half revolution. Secured to the gear 80 is a disk 81, to which theend of a link 81 is eccentrically pivoted. The other end of link 81 ispivoted to the cross-head 76. Thus when a roller 71 on one of the rods69 comes under the projection 77 and the gear 80 makes one revolutionthe link 81 and the cross-head 76 are drawn down, the projection 77,carrying With it the rod 69 until the rod is locked in its lowermostposi- 69 of this receptacle has now come under the projection 77 on thecross-head 76 and at the same time that the lower plunger-rod 42 ismoved up the intermittent gears 80 80 operate the link 81 to pull downthe crosshead 76, and the projection 77 thereon carries with it theroller 71, rod 69, and the arm 65, secured to rod 69, thus bringing thecap 67 down over the top of the bulb. W'hen the rod 69 reaches itslowest position, the hook 72 thereon catches over the latch 72, and therod is held in this position, while the crosshead 76 and projection 77are returned to their normal positions to repeat the operation on therod of the next receptacle. The base and the bulb are thus pressedtogether under heavy pressure, the springs 47 and 68 allowing for anyslight differences in the size of the bulb and base. When the. parts arein this position, air is admitted from the supply-pipe 54 throughpipe 53,pipe 49, to chamber 48, and from there through the openings in thereceptacle, the plunger-rod, and the sleeve 46 to the under side of thebase. From there the air passes up around the base and out the smallpassages 60, and not only assists in cooling the base and the cementtherein, but also carries out with it any gases which may accumulate inthe receptacle around the base. Water from the supplypipe 35 flows upthrough the hollow shaft 34 through pipe 57 to the chamber 56 in thereceptacle, which almost completely surrounds the base, and out by thepipe 58 and the wastepipe 59. The parts remain in this relation whilethereceptacle is moved around over three-fourths of a revolution of thesupporting member 1, and during this time the circulation of water coolsthe cement compound until it is quite hard. The roller 71 on the rod 69then engages the cam 75, and the rod is drawn down thereby just farenough to carr the hook 72 out of engagement with the latch 72, thespring 68 giving enough to permit this slight downward movement of therod. On further turning movement of the supporting member the dog 74engages the post 74 and the latch 72 is drawn back out of'the path ofmovement of hook 72. As the turning movement continues the roller 71moves up the inclined end of the cam 75 until finally it is released bythe cam, and the spring 71 pulls the arm 65 and the parts carriedthereby upward, the movement being cushioned by the-dash-pot 70. Thiscarries the cap 67 up off of the bulb, and the lamp is ready to beejected from the machine. On further turning movement of the sup ortingmember the roller 45 on the lower pun er-rod comes over the rod 85, andthis ro is then raised vertically by the cam 86. As the rod reaches itsuppermost position the groove 88 therein connects the pipes 89 and 63and air from the source of supply 90 flows through pipe 89, groove 88,pipe 63 to the pipe 62, which is arranged just back of the receptacle,and the blast of air from the pipe 62 blows the lamp over into. thechute 91, by which it is carried down to the belt-carrier 92. The cam 86then lowers the rod 85 to its former position, and the roller 45 on thelower plunger-rod passes ofi onto the cam 84. On further movement theroller 45 moves down the inclined portion of the cam, so that the lowerplunger-rod 42 is drawn down in the receptacle by the spring 44, and thereceptacle is ready to receive another lamp. It will thus be seen thatthe operation of basing the lamps is entirely automatic. One operatorassembles the parts and places them on the holders 11, and the finishedlamps are taken from the belt 92. The number of lamps that an operatorcan base in a given time is therefore greatly increased, and the cost ofbasing the lamps de creased. As the plungers 66 and 42 are arranged inaxial alinement, each base is secured on its bulb in exactly the properrelation. A
